CHARLES OARLSON, OF DEER TRAIL, COLORADO.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 553,332, dated January21, 1896.

Application filed March 29, 1895.

To all whom it may concern.-

Be it known that I, CHARLES CARLSON, a citizen of the United States ofAmerica, residing at Deer Trail, in the county of Arapahoe and State ofColorado, have invented certain new and useful Improvements in Car-Couplers; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the figures of reference markedthereon, which form a part of this specification.

My invention relates to improvements in car-couplers; and it consists ofthe features hereinafter described and claimed, all of which will befully understood by reference to the accompanying drawings, in which isillustrated an embodiment thereof.

In the drawings, Figure 1 is a horizontal section taken through thedraw-head provided with my improvements. Fig. 2 is a vertical sectiontaken on the line at a, Fig. 1. Fig. 3 is a cross-section taken on theline y 3 Figs. 1 and 2. Fig. 4 is a perspective view in detail of thegravity locking-block, shown without the rollers.

Similar reference-characters indicating corresponding partsin theseviews, let the numeral 5 designate the draw-head, to one horn of whichis pivoted the coupling-j aw 6, having a tongue 6' adapted to enter therecess of the draw-head. -Within the draw-head, and projecting upwardfrom the bottom thereof, is a keeper 7 having an inclined slot 7. Tothis keeper is movably attached a device 8, whose function is to lockthe jaw 6 in the coupled position. This device comprises a block havinga recess 8", adapted to receive thekeeper '7. The roof of this recessengages the face of the inclined keeper. The locking-block is attachedto the keeper by a pin 9 passing through the block and the inclined slot7. The block may be provided with antifrictional rollers 10 engaging thekeeper and adapted to facilitate the movement of the block which ridesthereon.

Serial No. 543.771. (No model.)

As the coupling-jaw 6 is forced inward by the draw-head of anapproaching car, the tongue 6 engages the block 8 and moves it upwardand rearward on the keeper sufficiently to allow the tongue to pass toone side thereof, when the block will return by gravity to its normalposition, thus locking the coupling-jaw in place.

. When it is desired to uncouple the cars, the locking device may beactuated by any suitable instrumentality. As shown in the drawings, apin 13 is connected with a chain 12, the pin being passed through thetop of the block.

.This chain enters the draw-head through a suitable opening 14 formed inthe top thereof. By pulling upward on the chain the lockingblock may bemoved upward and backward on the keeper sufficiently to release thetongue of the coupling-j aw, which will then move outward to theuncoupled position as the cars separate.

It must be understood that the lockingblock 8 may be used with orwithout the antifrictional rollers, as may be desired; neither do Ilimit myself to the exact construction shown, as I am aware that manymodifications may be employed without departing from the spirit of theinvention.

Having thus described my invention, what I claim is In a car coupler,the combination with the draw-head and pivoted coupling jaw having atongue adapted to enter the recess of the draw-head, of a slotted,inclined keeper located within the recess of the draw-head, and alocking block movably attached to the keeper and provided withanti-frictional rollers to facilitate the movement thereof,substantially as described.

In testimony whereof I affiX my signature F. T. FOLSOM, WM. HENDERSON.
